LET’S FIGHT AGAINST OCEAN POLLUTION 

 

THE Manta A COMPLETE, CORRECTIVE AND PREVENTIVE ANSWER TO FIGHT AGAINST PLASTIC POLLUTION

 

 

MTB & TSC

 

SINCE 2016, WE HAVE BEEN WORKING TOGETHER WITH THE SEA CLEANERS, USING OUR SKILLS AND KNOW-HOW TO FIGHT OCEAN POLLUTION. LIKE MTB, TSC’S AMBITION IS TO ACT FOR THE ENVIRONMENT WHILE SEEKING SOBRIETY.

 

 

 

« Acting for a pollution-free ocean is a vital need for life and a promise we make to our future. It also means defending an aspiration for beauty and freedom that drives us all. » Yvan Bourgnon, President and Founder of The SeaCleaners

 

 

 

 

 

THE 4 missions OF THE Manta

 

  • Collect waste in the water,
  • Raise awareness and preventing plastic pollution: possibility of welcoming 200 visitors on board,
  • Host scientific missions: providing useful information for research on plastic pollution: 50m2 of dedicated space,
  • Be a driver for the circular economy: find recycling channels at each stop.

THE MAIN DEVELOPMENTS OF THE BOAT

 

The size of the Manta has been reduced to simplify operations in the water but above all to increase its energy autonomy. The mass has been divided by 2 and the boat will be a catamaran. This reduction has also been achieved thanks to the development of a pyrolysis waste treatment unit, which has reduced the space required for waste storage.

 

In order to maintain a large amplitude of collection, waste collection nets will be deployed to collect up to 1m deep in the water over a trawling width of 46m.

ENERGY AUTONOMY

 

Thanks to its 500m2 of solar panels, its energy conversion unit, its 1500 m2 of sails and its 2 wind turbines, the Manta will reach an energy autonomy of 75%. The energy production will total 500kW, which will notably enable the on-board recycling unit to operate.

MTB RECYCLING UNIT

When moving through the water, the Manta will absorb floating waste with a minimum size of 10mm. Once collected by nets and conveyors, the 3 sorting operators will separate plastic and organic waste, metals and other potential waste.

 

The plastic and organic waste will then be shredded in an MTB BVR and dried before being sent to the pyrolysis unit. Waste that cannot be directly used for energy conversion will be stored on board and then processed on land. The vessel will have a storage capacity of approximately 50 tons.

HOW DOES PYROLYSIS WORK ?

 

The pyrogasification unit allows to obtain gas from plastics by heating them at high temperature (>700°C) in the absence of oxygen.

 

The obtained gas converted into electricity (turbine) will be used for the operation of the ship and the heat will be recycled for drying waste and other needs on board. Of course, the gaseous emissions will comply with the strictest European requirements.
